A facile synthesis of a mixture of the C-11 isomeric 3-oxo-7 alpha H-eudesma-4-en-9 beta.12-diol has been achieved from oxycarvone. The C-11 configuration of natural product is established through comparison of H-1 NMR spectra between synthetic 1b, or the mixture of 1a and 1b, and natural diol.

The first synthesis of (±) - 9 - oxoeudesma - 4, 11 (13) - diene - 7αH - 12 - oic acid methyl ester (1) has been described, employing the Ene-type chlorination with hydrogen peroxide / Vilsmeier reagent system as the key step.
